MOUNTING FOR RECOlLlNG-GUNS.

Specification of Letters Patent.

Patented April 1'7, 1906.

Original application filed April 13, 1905, Serial No. 25 0,0 79. Divided and this application filed July 6 1905. Serial No. 26 8,348.

To all whom it may concern:

Be it known that we, ARTHUR TREVOR- DAWSON, lieutenant of the Royal Navy, director and superintendent of Ordnance Works, and GEORGE THOMAS BUOKHAM, engineer, subjects of the King of Great Britain, residing at 32 Victoria street, Westminster, in the county of London, England, have invented certain new and useful Improvements in Mountings for Recoiling-Guns, of which the following is a specification.

This invention relates to mountings for recoiling-guns, and has for its object to provide an improved contrivance for automatically resisting the turning moment about the cradle-trunnions that arises when the gun recoils on firing.

In the accompanying drawings, Figure 1 is a longitudinal section; and Fig. 2, a transverse section taken approximately on the line 2 2, showing the aforesaid contrivance.

A is the gun, and K the cradle, which is carried by the trunnions 7c. The said cradle has on its under side the recess 7c for the reception of a spring-plunger k having its bottom curved or wedge-shaped at k and lying in a curved or wedgeshaped groove Z in the pedestal L of the mounting. The said plunger k is shown to be made in two superposed main parts, that are separated by belleville washers k for the purpose of imparting elasticity to the contrivance. The upper part carries the roller which bears against the under side of the gun, a small notch k being formed in the gun for the roller to normally rest in. We have also shown the lower curved part of the contrivance provided with a small roller k carried by a spring-bolt it so that when the gun advances to its firing position after recoil and the upper roller resumes its position in the notch k of the gun the said spring-bolt will operate to insure that the lower curved portion of the plunger k is lifted out of contact with the curved groove Z of the pedestal,-so that the gun and cradle are free to turn about the trunnions during the movements of elevation or de-' wedge-like action between these parts that counteracts the tendency of thegun and cradle to move about the trunnions under the influence of the longitudinal displacement of the center of gravity of the system when the gun recoils.

What we claim, and desire to secure by Letters Patent of the United States, is

1. In a quick-firing gun, the combination with the gun-cradle and the mounting in which said cradle is trunnioned, of a springplunger made in two superposed parts mounted in a recess in the under side of the cradle, a curved or wedge-shaped portion on the lower part of the said plunger lying in a curved or Wedge-shaped groove of the mounting, a roller carried by the upper part of said plunger normally engaging with a slight notch or recess in the gun, springs interposed between the two parts of the plunger, and a spring-roller mounted in the lower part of the plunger and bearing against said groove in the mounting substantially as and for the purpose specified.

2. In a quick-firing gun, the combination I cradle, a curved or wedge-shaped portion on the lower part of said plunger lying in a curved or wedge-shaped groove of the mounting, a roller carried by the upper part of said plunger normally engaging with a slight notch or recess in the gun, means for detachably connecting the two parts of the plunger with freedom of motion between them, springs interposed between the two parts, means for retaining the plunger in place within its recess Without impediment to its movement, and a spring-roller mounted in the lower part of the plunger and bearing against said-groove in the mounting substantially as and for the purpose specified.

In testimony whereof we have hereunto set our hands, in presence of two subscribing witnesses, this 21st day of June, 1905.

Witnesses:

JOHN S. SHIELns, ALFRED PEAKs.
